SEPARABLE NON-SLIPPITNG ATTACHMENT FOR SHOES.

Specification of Letters Patent.

Application filed December 21, 1917. Serial No. 208,202.

To all whom it may concern:

Be it known that I, REINHOL-n KALrURs'r, a citizen of the United States, residing at Clementon Heights, in the county of Camden and State of New Jersey, have invented certain new and useful Improvements in Separable Non-Slipping Attachments for Shoes, of which the following is a specification.

My'invention relates to improvements in means for preventing shoes from slipping and has as its principal object the provision of a separable attachment which may be readily applied to the heel -of a shoe whenever desired and having separable means whereby the said attachment may be held firmly in position and yet'readily removable.

I attain these and other objects by means of the novel design, construction and combination of parts hereinafter described and shown in the accompanying drawings, wherein,

Figure 1 is a side view showing the attachment in position on the heel of a shoe;

Fig. 2 is a plan View of the device;

Fig. 3 is a vertical sectional view of the device;

Fig. 4 is likewise a vertical sectional view of the device taken on the opposite side to Fig. 3;

.Fig. 5 is a plan view of the locking bar, and Fig. 6 is an end view of the attachment, part thereof being broken away, illustrating a method of locking the device in position by means of a screw.

Similar reference characters refer to similar parts throughout the drawings.

Referring to the drawings in detail the invention consists of a frame a, constructed of a single sheet of suitable material, substantially of the contour illustrated and adapted to fit snugly over the heel of a shoe 0. Formed integral therewith are the upwardly extending lugs or parts I), 0 and d as shown. The lugs b are so formed that they will grip tightly the corners of the heel, being made slightly beveled for that purpose in addition to being interiorly corrugated. The lugs or parts 0 and d are adapted to fit firmly against the rear sides of the heel.

Apertures e, substantially oblong in form, are cut out or stamped in the said frame a, as illustrated, the side portions thereof being bent and extended outwardly and downwardly forming a series of Spurs 6, said spurs 6 extending in a horizontal position to said frame a. Apertures f, substantially square in form, are likewise out out or stamped in the said frame a, as illustrated, the end portions thereof being bent and ex tended outwardly and downwardly forming a ser es of spurs f, said spurs f extending in Said a parallel position to said frame a. spurs e and f projecting from said frame a an equal distance.

The lug 0 on the left side of the said frame a, whichlikewiseterminates in a rounded pocket at as particularly illustrated in Fig. 3, the opening 0" being cut vertically in the" lug 0 and the opening (Z being cut longitudinally in the lug d, the pockets 0 and (i being in parallel alinement to each other.

A separable horizontal locking bar it is provided as a preferred means for holding the device firmly inposition on the heel. Said bar It has the notches i and p on either side thereof and near the ends as illustrated, in order to engage the openings 0 and (Z and substantially in the center thereof and integral therewith the extending projection g terminating in the prongs j and k to engage with the heel of the shoe.

A portion Z of the frame a may be extended beyond the outer edge of said frame a as particularly illustrated in Fig. 6. This extending portion Z may be turned upwardly on a line paralleling the said outer edge of said frame a so that it will fit against the heel of the shoe and may be secured thereagainst by means of a screw m having the screw head 12, through a suitable opening in said portion Z.

Openings 9 are also provided in the frame a as shown. Means may be inserted in said openings to secure the device to the underneath portion of the heel.

To secure the attachment in place after it is placed over the heel of the shoe, the parts 6 gripping firmly the corners of said heel and the lugs 0 and d the rear sides thereof, the separable horizontal locking bar it is first inserted in the opening 0 and then forced downwardly into the pocket 0 The bar It is then turned by means of the notches p in the said pocket 0 securely positioning same Patented Nov. 12,1918.

. frame (1 is provided with the opening 0 terminating? in the rounded pocket 0 as particularly illustrated in Fig.4. A like opening d is provided in the lug d on the right side of therein thereby bringing the notches z in position to be inserted in the horizontal openings d in lug (Z. The bar is then forced through said opening (Z until it rests in the pocket cl. This action causes the prongs j and is to engage the outside end of the heel, thus securely locking the attachment in position. To disengage and remote said bar it the said bar is Withdrawn from the pocket (15 through the opening (P, the prongs j and is Withdrawn from the heel, the bar then being turned until it can be withdrawn from the pocket 0 through the opening 0. Said bar it extends sufiiciently beyond the outside limits of the heel to enable the operator to grasp an end thereof to disengage and remove it.

In lieu of said locking bar it the attachment may be held firmly in position on the heel by having a portion Z thereof extend beyond the outside line of said device and then bending this portion Z upwardly against the end of the heel and securing same thereagainst by means of a threaded screw through a suitable opening therein.

Having thus described my invention What memos I claim as new and desire to secure by Letters Patent is:

A separable non-slipping attachment for shoes, comprising a frame, front and rear 1 extending from and integral with said locking bar terminating in prongs, said prongs adapted to engage the rear portion of the said heel, whereby said locking bar may be secured in said pockets and on said heel to maintain said attachment in position on said heel.

In testimony whereof I affix my signature in presence of two Witnesses.
